Merge branch 'ixgbe'

Aaron Brown says:

====================
Intel Wired LAN Driver Updates

This series contains several updates from Alex to ixgbe.

To avoid head of line blocking in the event a VF stops cleaning Rx descriptors
he makes sure QDE bits are set for a VF before the Rx queues are enabled.

To avoid a situation where the head write-back registers can remain set ofter
the driver is unloaded he clears them on a VF reset.

Alexander Duyck (2):
  ixgbe: Force QDE via PFQDE for VFs during reset
  ixgbe: Clear head write-back registers on VF reset
